Rails-Heroku图像找不到正确的路径 [英] Rails - Heroku images not finding right path

问题描述

我正在使用Rails 5.2.0，并已部署到Heroku.我有使用以下调用加载的图像:

I'm using Rails 5.2.0 and have deployed to Heroku. I have images being loaded using the following call:

...link_to image_tag("/assets/avatar.png", class: "img-responsive")...

在我的本地计算机上，它们可以正确加载.

on my local machine and they load properly.

目录结构为:

my_project
    app
    |    assets
    |    |   images
    |    |   |    avatar.png

但是，在Heroku上，图像未加载.我检查了其他帖子，但是不确定是否需要修改我的Gemfile/production.rb等.我也尝试过将Heroku上的路径更改为

However, on Heroku, the images aren't loading. I have checked other posts but am not sure if I need to modify my Gemfile / production.rb etc. I have also tried changing the path on Heroku to

...link_to image_tag("app/assets/avatar.png", class: "img-responsive")...

将/app添加到路径，但这也不起作用.

adding the /app to the path but this hasn't worked either.

我的问题是我是否只需要更改路径，以便Heroku可以找到图像.如果是这样，那么路径应该是什么? Heroku在运行Rails应用程序时从何处开始"路径?

My question is do I need to just change the path so Heroku can find the images. If so, what does the path need to be? Where does Heroku "start" the path from when a Rails app is running?

还是需要做一些其他事情以使Heroku查找并加载这些图像?

Or is there something else that needs to be done to allow Heroku to find and load these images?

推荐答案

下面将是这样

<%= link_to image_tag("avatar.png", class: "img-responsive"), url_path %>

查看 image_tag 关于image_tag的工作原理.

Look the image_tag for how image_tag works.

将production.rb文件config.assets.compile false更新为true

# config/environments/production.rb
...
config.assets.compile = true
...
